A total of 154 of Escherichia coli (E. coli) isolates were isolated from faecal specimens of healthy cattle (n=100). Serotyping of 154 E. coli isolates indicated that 112 (72.72%) isolates were typeable, 28 (18.18%) untypeable and 14 (9.09%) were rough. The most predominant serotype observed was O22 followed by O56, O60, O120 and O1. Antibiogram pattern using a total of 25 different antibiotics indicated that high resistant was present against clindamycin, metronidazole and penicillin followed by cephalothin, neomycin, kanamycin, cephalexin, streptomycin, furazolidone and tetracycline antibiotics. The amplification of tet(A) and tet(B) resistant determinants by PCR resulted in generation of 372bp and 228, respectively. The tet(A) gene was predominant gene compared to tet(B) gene. This study using pheno-genotypic characterization indicated the presence of antimicrobial resistant E. coliisolates amongst healthy cattle, emphasizing that effective strategy should be applied to persist the efficiency along with ideal usage of novel antibiotics though minimizing the risk of antibiotic resistant bacteria.
